Yrellea's offer to the Dragon Tiger Palace

While Azaroth was seated in his room, he commanded Bianca and Josephine to act in such a manner that the Royal Family of the Sinyalian Kingdom would be hostile to its Noble Families.

This plan was working wonderfully. Bianca had now sent her cousin back.

Piero believed that he had already spent some spicy nights with Bianca and was on cloud nine. He had no idea that what he experienced was merely his dreams and imagination. An illusion to some extent. It never actually occurred in real life.

The illusion and those dreams were so realistic that even if someone told him the truth, he wouldn't believe it.

He remembered Bianca's flirtatious actions. There was no way this whole thing was a lie. Also, even if he did find out the complete truth and accepted it, he would not be able to do anything about it.
